I am due to start a new job in about four weeks. I suffer from mental health issues (which my new employer knows about as I declared them as a disability) which I am on medication for. I feel I would also benefit from therapy and after being on a waiting list have been offered a counselling slot on Tuesdays at 6pm. However, my new job is full time 10am-6pm. I did have a verbal agreement with my new employer that if hypothetically necessary I could work 9am-5pm to enable me to attend disability-related medical appointments, but at the time this wasn't imminent because I hadn't been offered the therapy slot at that point.
My question is WIBU agree to the therapy slot time before confirming with my new employer that I can slide my shift an hour earlier one day per week to enable me to attend counselling? I'm not starting my new job for another few weeks and this therapist and I may not even be a good match, so I might decide not to go back to see this particular therapist again once I've had the initial appointment. But also I feel stressed at the thought of agreeing to the therapy slot without being 100% sure I'll be able to attend after I start my new job, although I did have the verbal agreement with my manager around flexibility with my hours for appointments.
